The first interview was a "technical interview" with no indication of this. I walked into the interview not knowing it would essentially be a quiz and little to no questioning about my actual resume. To be fair it was general engineering questions most mechanical engineers will learn in college. They asked me to draw a few graphs, fill in some tables, and to take apart a "click pen" and to describe what each piece was made of and the manufacturing process used for each part.

Not a good experience. I felt very disrespected in terms of both my time (they wanted me to interview for 7 hours straight) and the interviewers’ questions/responses during the interview process. The questions don’t make sense/are vague and when I tried asking for clarification they would only repeat themselves. When I was giving answers, they would respond with “are you sure?” And “are you really happy with that answer?” And did not go on to correct me or give feedback. Very low energy from all of the engineers I interviewed with (who were all very white and very male I might add). Did a super weird role play exercise which was unnecessarily intense and quite frankly, a waste of my time. I have interviewed with and received offers from top engineering companies, 2 of which had an intense technical portion with a follow up panel presentation (and I did not ever feel disrespected, treated unfairly, or like I was being strung along with no regard for my time like I did at Lutron). I don’t know if this company is struggling to hire, but they must be with how bad this experience was. By the time I went on to second round of interviews I was already over it and knew this company was not for me. I went forward with it because the interviews were prescheduled and I did not want to appear flaky, but in hindsight, I should have cancelled it before enduring 2 more hours of feeling talked down to and not listened to. I think they forget that an interview goes both ways. Would not recommend.
